The Forbes ranking   is an annual, reliable ranking of companies that have increased their value most dynamically in recent years. The title  "Forbes Diamond 2024" is a confirmation of the position among the best companies on the Polish market.

The awarded companies are divided into three categories according to sales revenue in the last fiscal year: small companies with sales revenue from PLN 5 to 50 million, medium-sized companies with sales revenue from PLN 50 to 250 million, large companies with sales revenue above PLN 250 million. Dun & Bradstreet Poland's credit information agency collected data from companies that filed reports to the National Court Register for the period 2022–2018 on time. On this basis, this year's record-breaking list was created, exceeding over 20 thousand companies to which Dun & Bradstreet Poland awarded a positive credibility and risk rating for cooperation, have high current liquidity and do not have arrears with payments to contractors. Companies meeting all of the above conditions additionally had to demonstrate a positive financial result and equity value. Financial institutions, such as banks, were eliminated due to significant differences in balance sheet categories between them and manufacturing and trading companies. The Forbes Diamonds list includes companies that have achieved the largest average annual increase in value – at the level of 10% or more. On the other hand, entities that have recorded a negative change in valuation in at least one of the last three years or the valuation value has not maintained the character of continuous growth have been removed from the list.
